INSTALLATION FOR PENDANT MODELS
PENDANT-MOUNT INSTALLATION
1. Install the pendant dome mount. Refer to the instructions supplied with the mount. If
the mount is outdoors, make sure it is properly sealed to keep moisture out.
2. Bring the wiring for the dome through the mount. Refer to the
Wiring
section.
3. Refer to Figure 10. Loosen the thumbscrew inside the back box and open the hinged
door.
4. Screw the back box into the mount and bring the wiring into the back box. If outdoors,
apply the provided pipe sealant to the threads on the back box.
5. Attach the wiring to the back box. Refer to the
Back Box Connections
section.
6. Install the dome drive. Refer to the
Dome Drive
section.
7. Remove the O-ring and O-ring lubricant from the parts bag. Lightly apply lubricant to
the O-ring so that it is just moistened; do not use excess lubricant. Install the O-ring in
the groove on the trim ring of the lower dome.
8. Refer to Figure 16. Hanging down from the back box is a short cable (the trim ring
leash). Hold up the lower dome near the back box so that the trim ring leash touches
the lower dome. Line up the two screw holes in the trim ring of the lower dome with
the two screw holes in the back box. Place a finger on the edge of the trim ring where
the leash touches the lower dome.
9. Look inside the lower dome and note which of the six retainer screws is closest to your
finger. Remove this screw and attach the trim ring leash to the screw. Reinstall the
screw securely and make sure the leash will hold the lower dome.

NOTE:
If outdoors, apply
Duct Seal inside the pipe
portion of the back box to
prevent moisture or cold air
inside the mount from enter-
ing the unit and causing
condensation on the dome.
Make sure no moisture has
condensed inside the unit
before installing the lower
dome. Duct Seal can be
purchased through local
electrical supply houses.
